"Jeff has the rare ability to both inspire and teach people how to be their best when it counts. Few in the world of sport psychology have earned and merited such universal respect."
- Dick Gould, Former Stanford University Coach, 6 time NCAA Champion
"Yesterday I won the National Men’s 55 and over National Indoor Championships of Great Britain and the reason I won is because I spent 6 weeks working on the mental coaching strategies in Jeff Greenwald’s program."
- Michael Appleton, National Champion Men's 55 Great Britain
"Jeff ’s competitive experience and his climb to number one in the world in the 35s brings depth, dimension and authenticity to his voice and to his suggestions. Jeff ’s approach to fearless tennis represents a real contribution to the field of applied sport psychology and is helpful for every serious competitive tennis player."
- Jim Loehr, Ed.D. CEO Human Performance Institute
"This course really helped me stay focused in big matches. I would not have been able to beat two players I had previously lost to without the techniques in this program. I was able to think about playing the ball and not focus on the score, which helped me play loose and play my best when it counted most."
- Caroline Pozo
"Jeff’s focus course helped me stay positive and feel more in control. Now when my mind wanders I am able to refocus it on the task at hand quickly. Understanding that our thoughts create our feelings and behavior has helped me focus on what is relevant and I am winning more than ever."
